I'm not convinced that's a BT cabinet in the centre, there's no reason for it to have a warning sticker on it about electricity.
Yes, and the green cabinets are not a type I have seen before. The end one is an old cabinet with new doors, almost as if it has been repurposed. The centre one is not vented either.
I will investigate further to see what I can find out.
Just thinking out load (always dangerous on a forum!) - is it in any way possible or probable that these are
former Openreach cabinets that have been “taken over” as part of PIA or other arrangement to an AltNet (possibly Community Fibre given the location and grey cabinet type) to house some of their active equipment - hence the updated doors on the green cab?
Otherwise it may just be Virgin M.
